RADIOLOGY: PANCREAS: Case# 32893: INTRAABDOMINAL LIPOMA. 63 year old woman. 1. Enlarged, ill-defined pancreatic head consistent with clinical diagnosis of pancreatic carcinoma. The adjacent infiltrative changes are consistent with pancreatic carcinoma, however, there may be a superimposed component of pancreatitis. 2. Nodules in the right lung base suspicious for metastatic disease. 3. Large fat density tumor in the abdomen that is unchanged in size and appearance. This most likely represents a benign lipoma, especially considering the stability over 18 months, however, liposarcoma cannot be excluded radiographically.
